Multipath interference disrupts wireless signals, causing issues like TV ghosting and fading. Now, researchers have developed a passive metasurface that overcomes traditional filtering limits. Using a ...

As the number of higher-throughput applications grows, so does the need for a wider bandwidth and network coverage in wireless systems. Given limited spectrum allocation, wireless communication ...

Multipath mitigation is a critical area of research within Global Navigation Satellite Systems (GNSS) that addresses errors arising from signal reflections off surfaces before they reach a receiver.

Interoperable multipath hemispherical map (MHM) using overlap-frequency signals across constellations. The top panel shows the flowchart for modelling and correcting multipath in interoperable MHM.

Accurate smartphone positioning in dense urban environments remains challenging due to signal blockage, multipath effects, and unreliable satellite visibility. This study presents a new positioning ...

At the signal layer, the approach draws simultaneously on multiple components of 5G transmissions to maintain lock even when reflections dominate. Rather than losing precision when signals weaken, the ...

This video presents a study in which researchers developed a passive metasurface that uses a time-varying interlocking mechanism with metal-oxide-semiconductor field-effect transistors to selectively ...
